摘要：

A recent large-amplitude fluid theory of electrostatic ion-acoustic double layers [J. Plasma Phys. 40, 163 (1988)]. is shown to be adaptable to the case of stationary double layers in a two-ion plasma with kinetically determined ions. The influence of ion temperature and light-ion concentration on the double-layer structure is studied and directly compared with fluid theory predictions. The role of the ion trapping parameter is examined. It is found that departure from fluid theory can be explained as being due to the influence of ion Landau damping and/or ion trapping. Extension of the theory to multielectron and multi-ion plasmas is pointed out. © 1990 American Institute of Physics.
